A St. John’s-wort from Sharon SC

a thick groundcover vine, ~ 10-12 inches high. a lone yellow flower was present, see below. it is growing in an abandoned bed in a school yard – dry, partial shade. the “powers that be” are about to bulldoze the flower beds to replace them with grass. I am trying to save what I can.


Hi Sharon,

your plant is a nice ground cover species, and is called Hypericum calycinum.  It is widely grown, and the flowers are quite beautiful.  It is related to the more common wild St. John’s-wort species, all Hypericum.

You can find out more about it here, from a North Carolina site: http://www.ces.ncsu.edu/depts/hort/consumer/factsheets/groundcover/hypericum_calycinum.html

I hope this helps!
